The 3Racing SAK-D5638 Sakura D5 MR Graphite Main Chassis is engineered for racers focused on setup refinement. Produced from precision-cut graphite, the plate increases torsional rigidity while reducing inertial weight, which gives a more predictable response to damping and roll adjustments. It interfaces directly with the Sakura D5 MR mounting scheme to preserve geometry for accurate tuning.
Graphite offers a favourable stiffness to mass ratio that benefits transient response and mid corner behaviour. The SAK-D5638 provides a firmer backbone for suspension work, allowing tuners to exploit shock and anti-roll bar settings more effectively.
The chassis layout maintains factory mounting points and component clearances for the Sakura D5 MR, enabling repeatable setup changes. Its structural profile supports centralised mass placement and improved pitch control, which aids fine tuning for different track surfaces and driving styles.
Engineers and serious racers will find the 3Racing SAK-D5638 a useful base for setup development and consistent on-track performance.
